How To Make A Single Serve Rice Krispie Treat
See the recipe box below for ingredient amounts and full recipe instructions.
To make a single Rice Krispie Treat, start by melting butter and marshmallows together in the microwave until soft and smooth. Stir in the crispy rice cereal, making sure it’s fully coated in the marshmallow mixture. Press the mixture into a buttered dish, spreading it evenly, then let it cool before enjoying.
No Microwave?
Melt the butter and marshmallows in a small saucepan over low heat, stirring until smooth. Then mix in the cereal and press into a dish as usual.
Expert Tips
- Avoid Overheating: Remove marshmallows from the microwave as soon as they melt to keep them soft and easy to mix.
- Stir Gently: Mix lightly to keep the cereal crisp.
- Press Lightly: Avoid packing too firmly for a soft, chewy texture.
Frequently Asked Questions
Yes. Double the ingredients, but you may need to microwave the marshmallows a few seconds longer to fully melt them.
